To all 'whomz't may concern.'V .Y Beit-known that I, PETERVN. .MADsEN, a citizenV of theUnited States, and a resident of the city of Detroit, county of Wayne, and State of Michigan, have :invented certain new and useful Improvementsin Automobile-Locks, of which the following is a specification. f-

'My invention relates to improvements' in automobile locks, `and has for its object Vthe 'provision of a deviceY of this character 'eluded in the construction.v

through the medium of which an automobile may be readily and easily locked against surreptitious removal, andfurther, a device which will Vbe o f durable and economical construction, and highlyeiicient in use,

, Other objects will appear hereinafter; The invention consists lin the co mbina tions and arrangements of parts hereinafter l described and claimed.

The invention will be bestlunderstood by reference to the accompanying drawings forming a part of this specification,V and in which, V

Figure l is a central section through locking device embodying the invention showing the same applied tothe control lever of an automobile, y

Fig. 2, a view similar to Fig. 1 showing thel device applied to the starting pedal of an automobile, p

The preferred form of construction as illustrated' in the drawings, comprises a com- Y Vbination lock'consisting of a `casing 7 in( which is rotatably mounted a plurality of shafts 8 to which are fixed ydisks 9 inclosed `in said casing. Washers 9 are arranged at opposite sides of each disk 9 1n order to 'specification of Lettersrain.- 5 *Patented 06f, 26,'.1920'f5 i Application ilediulyV A19, 1917.7' `Serialllloi, i 1

i thel rear lwallof The I of vsaidfcasing' is' formed 'withalc'ircular Opening 13.

for the snug reception j of [the reduced circularly formed vendof the Vbar: 12.,v as seenl in the several views. Formed infl'said bar adjacentvsaid @11d-thereof is a' circum'" ferent'ialgroove 14k, vadapted, after 'the endi ofthe bar has been'inserted to pos'itiongbe` tween the disks9to permit, of rotative adjustment of said disks in order to lock the bar in position, as clearlyseen in Figs. l and combinationfjof said disks wherein the'` notches 10 thereof; are in'regi'strat-ion as? seen in Fig. 4,' the p'eripheries of said disks' j will engage behindtheftriangularly formed A end portion 1l A of -gthebar and'thus lockth'e f Samen in position v"Subsequent :detachment of 'thebar maybe effectedjgon'ly upon rota JV` tive adjustment of said disk's to secure the proper ,combination-or adjustment thereof o operative registration. Such rotative ad-v wherein the notches 10 will Aagain be in cojustment of said disksis effected by means `v of eXteriorly positioned v finger pieces, 15 which are pointed atonev side for copera- -tion with graduations 16 karranged upon the front sid'e'ofy the casing.. The combination, Vthat is the proper positioning of the linger pieces l5A relativeto these graduatio'ns 16, 1

will/be. known only to the, fown'erof the may be effected only 'by the owner or opautomobile-so 4that operation of. they `lock erator ofthe automobile.

the device'I being suitably mounted Cream ychored Vadjacent the lever, and said lever being formed withV an'opening 1'8 for Vthe insertion of the locking bar therethrough.

' When the locking member kis 'in engagement with the lever thesame will be positively cluding shifting of the gears and hence operation of theu automobile. Or the .device may be used in. connectionwith the starting pedal of the automobileas seen at 19. In this use the combination lock will be suitsuitably arranged bracket 20, lsaid pedal 'being formed with an opening 21"for engage ment with the locking member.- The lock] locked againstl pivotalmovement, thus pre.

lably mountedladjacenti said pedal as on a lock except When it is desired to lock the au- Y tomobile. In this event the locking member Will be inserted through the' lever or pedal to be locked and then into the combi,-

nation lock to which the same will be fastened by proper manipulation ofthe finger pieces 15. When the locking member is thus engaged With pedal 191 the'latter will be locked against depressionand hence the automobile Will'be locked against operation parting from the spirit of the invention. I,

therefore, do not wish to-be limited tothe precise details of constructionl set forth, but desire to avail myself of such variations and modifications. as come Within. the scope of the appended. claim.- y l f Having described my invention what I claim as new and desire tosecure by Letters Patent is.:

i 'In an automobile lock, the combination with a movable controlmember of the automobile to be locked,said member having an opening therein.; a housing surrounding said control member Vand `having openings in opv positesides thereof arrangedto aline With the-opening in said control member; a locking member adapted to project through the openings in said housing and the opening in said control member to lock the latter against movement; an anchored combination lock; a casing for said lock having openings therein alined- With said housing openings and through 'Whichsaid locking member is 40 adapted to pass; 'a plurality of disks rotatably mounted in said casing, having notches in their peripheries adapted, when` said disks are' adjusted yto a certainposition; to permit thev passage into said casing of one end of said locking member; a circumferem tial groove insaid locking member adaptedv for` engagement by'saidV disks when the'latter are turned from said position; means for maintaining said disks inV alinement with the operative plane of said groove While said locking member is detached; eXteriorly positioned finger pieces for rotatably adjusting said disks; and graduations ar- Y ranged on saidl casingfor coperation with said finger pieces and the Vadjustment thereof, substantially as'described; i

In`testimony whereof I have signed my name to this specification inthe presence of two subscribing'vvit'nesses'.
